To all whom, it may concern.-

Be it known that I, ISAAC J ENKS MARsH, of Deer Park post-oflice, in thecounty of York, in the Province of Ontario, Canada, have inventedcertain new and useful Improvements in Reel-Ovens, of which thefollowing is a' specification.

My invention relates to improvements in reel-ovens; and the object ofthe invention is, first, to devise an economical means for heating theoven in which none of the products of combustion will enter thebaking-chamber, and, secondly, to devise a simple means for removing theproducts from the oven; and it consists, essentially, first, of aheating drum extending through the oven and provided with an exit-flueand a heating means for the drum located, preferably, at one end thereofand arranged so that the products of combustion are carried through thedrum, the reel being secured on the drum and suitable means beingprovided for rotating the drum, and, secondly, of removable shelvessupported by rollers on rails on the pivotal shelves and extension-railsextending through the oven door opening, whereby the removable shelvesmay be successively withdrawn, the parts being arranged and constructedin detail, as hereinafter more particularly explained.

Figure l is a perspective view of the outside of the oven, showing onemeans for driving the drum and means for locking the pivotal shelfpreparatory to withdrawing the removable shelf. Fig. 2 is across-section of the oven. Fig. 3 is a longitudinal section. Fig. 4 is adetail of the removable shelf.

In the drawings like letters of reference indicate corresponding partsin each figure.

A is the casing or wall of the oven, which is formed in any preferredmanner and of any preferred material, and B is the fire-chamber,provided with the usual fire-grate b and firedoor 6 and ash-door 72Although I show the fire-chamber, which may be adapted for coal or wood,it will of course be understood that I do not wish to confine myself towhat fuel may be used, as gas or fuel-oil or a blast-furnace may beused.

0 is a drum, which is preferably of a large diameter and is journaled inroller-bearings c in the end walls of the oven.

D are arms secured on the rings cl, which are preferably secured to theperiphery of the drum.

E are the pivotal shelves, which are pivotally connected to the outerends of the arms D and are provided with rails e, the form of theseshelves or supporting-arms being such as is usually made in reel-ovens.Of course the cross portion connecting the ends may be made lighter andof open-work or cross-bars,- as may be desired.

F is the removable shelf, which is'provided with end rollers f, asindicated, which'rest on the rails e, hereinbefore referred to.

Gr is a gear, preferably a worm-gear, with which meshes the worm G,which is located on the shaft g, journaled in suitable bearings andderiving movement from any suitable source of power. I

H is the exit-flue, which is provided with a flange 72 having aninwardly-turned portion designed to fit over the end flange c of thedrum (1, and it is a supplemental flange located to the inside of theflange cand secured to the inturned portion of the flange it.

I is a supporting-bracket for the flue H. The flue H is preferably heldstationary, and the drum rotates the flange c, rotating within theflange it, as will appear.

J represents rails located at the bottom of the door-opening J of theoven and opposite the rails of the shelves, such rails J extending inclose proximity to the path of the outer edge of the shelf as itrotates.

K represents plungers extending through' the end walls of the oven andprovided, preferably, with forked ends it, and L is a lever secured onthe end of the crank-rod Z, which is pivoted on the brackets Z on theouter wall of the oven. There is a crank-rod on each end of the ovenconnected to the plungers, and the crank-rods are connected, so as tooperate in unison, by the links Z connected to the central pivot-lever Zhaving arms of equal length.

It will now be seen that by manipulating the lever L the forked ends itmay be thrown underneath each end of the supporting-shelf E, and therebyhold such shelf stationary preparatory to the removal of the shelf F,which can be drawn outwardly, the rollers f passing outwardly over therails e J. This operation can be done successively to feed the shelvesinwardly or outwardly as the drum and reels are rotated and the shelvescome opposite the door-opening.

Of course I do not show any door for the opening; but it will of coursebe understood that the usual door will be provided.

The great advantage in my construction is that none of theproducts ofcombustion can get into the baking-chamber and yet the oven may beadequately heated.

'What I claim as my invention is- 1. In a reel-oven, the combinationwith the baking-chamber provided with suitable walls, of the drumjournaled in the walls, havingits ends projecting through said walls,means connected to one of said ends for-rotating the drum, armsconnected to the drum, shelves carried by said arms and means forheating the interior of the drum.

2. In a reel-oven, the combination with the baking-chamber provided withsuitable Walls, of the drum journaled in said walls and having its endsextending therethrough, means secured to one of said ends outside thewalls of the baking-chamber for rotating the drum, arms connected to thedrum, shelves carried by said arms, heating means at one end of the drumand a stationary flue at the other end, said flue having a flange havingits edge bent to form an annular groove and the said drum having aflange adapted to rotate in said groove, substantially as described.

3. In a reel-oven, the combination with the baking-chamber provided withsuitable walls, of the drum journaled in said walls and having its endsextending beyond the same, rings secured to the drum, arms carried bythe rings, shelves pivoted to the arms, removable shelves carried bysaid pivoted shelves, heating means at one end of the drum, a stationaryflue at the other end of the drum, a worm-wheel secured to the drumoutside the baking-chamber, a worm-gear meshing therewith and means forrotating the worm-gear.

4. The combination v with the reel and shelves hung thereon, ofreciprocating plungers passing through the walls of the oven and meansfor simultaneously throwing such l plungers in under the shelf when itarrives opposite the bottom of the oven-door.

5. The combination with the reel and shelves hung thereon, ofreciprocating plungers extending into the oven, a lever forreciprocating one plunger and link connections from said plunger tothe-other plunger whereby when the lever is operated both plungers willbe forced into or out of the oven, substantially as described.

6. In a reel-oven, the combination with a baking-chamber provided withsuitable walls, of the drum supported in the walls and extendingtherethrough and designed to form a conduit for the products ofcombustion, the heating-chamber located at one end of the drum andcommunicating therewith, a flue connected to the opposite end of thedrum and a reel supported upon the exterior of the drum as and for thepurpose specified.

7. In a reel-oven, the combination with the baking-chamber provided withsuitable walls, of the drum supported in the walls and extendingtherethrough and capable of radiating heat outwardly into the chamber, aheating-chamber communicating with one end of the drum and a flueconnected to the opposite end of the drum and a reel supportedperipherally outside of the drum as specified.

8. In a reel-oven, the combination with the baking-chamber provided withsuitable walls, of the drum supported in the Walls extendingtherethrough and capable oi radiating heat outwardly into the chamber, areel supported peripherally outside of the drum and means for interiorlyheating the drum as and for the purpose specified.
